Deep diver planned to explore bottom of Marianas Trench

China has been trying to explore every frontier in science and technology, from outer space to the elements of an atom.

Now, Chinese scientists are determined to probe secrets found in the deepest parts of the oceans as they develop a manned submersible capable of reaching the bottom of Marianas Trench in the western Pacific Ocean. At a depth of 11,034 meters, it is the deepest trench on Earth.

The submersible, which has yet to be named, is being designed at China Ship Scientific Research Center in Wuxi, Jiangsu province and will conduct its first trial within five years, according to Wang Junli, deputy director of science and technology at China Shipbuilding Industry Corp, the world's largest shipbuilder and parent company of the center.
